Hello,
I can nicely manipulate the color (and style, thickness etc.) of TDiagramLine after it has been drawn in a diagram (in child classes).
However, I wonder how to change the line properties while drawing: I can change thickness, but changing the color does not reflect in the mouse-drawing operation.
Also overriding TDiagramLine DrawLine, InitDrawer, UpdateDrawing (to set TLineInfo or Dgr)Canvas Pen.Color) does not help: the line color during mouse-drawing stays black.
How to do this?
Thanks, regards, Wilfried
